Car won't run unless you have gad pedal depressed and stay on it when you let off it shuts off. then at other times it will start and run until you push the gas pedal then it shuts off. issues started with a code for actuator, throttle body was replaced. Now pulling codes:
P0100
P0110
P1120
P1121
P1125
P1126
P1300
Where should i start?

Here's a breakdown of the error codes you provided and their possible meanings:

P0100 - Mass or Volume Air Flow Circuit Malfunction:

P0110 - Intake Air Temperature Circuit Malfunction:

P1120 - Throttle Position Sensor Circuit:

P1121 - Throttle Position Sensor Range/Performance Problem:

P1125 - Throttle Control Motor Circuit:

P1126 - Magnetic Clutch Circuit Malfunction:

P1300 - Igniter Circuit Malfunction (Bank 1):

So I would clear all codes and then just turn the key on without starting the engine to see which hard codes come back this is where we should start. Please let me know.
